... coulomb=6.24151*1018 electrons. Therefore, 1 amp means that 6 followed by 18 zeros, or 6 billion billion electrons are flowing past a point in one second. Since 1 Coulomb=6.24*1018 electrons, each electron has a charge of 1/(6.24*1018) =1.6*10-19C. When measuring current in a circuit, we put an amme ...

Nanofluidic circuitry
Nanofluidic circuitry is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic counterparts. Its typical characteristic dimensions fall within the range of 1–100 nm. At least one dimension of the structure is in nanoscopic scale. Phenomena of fluids in nano-scale structure are discovered to be of different properties in electrochemistry and fluid dynamics.
